v1 alpha

Timewise v1

The code is now conceptually comprised of three parts:

1. Download the data
2. Process the single exposures using AMPEL
3. (optionally) Export light curves, plots, etc

All parts are configurable, thanks to pydantic and the AMPEL job file layout.
A test suite makes sure that results are consistent with version zero (specifically, v0.5.4, which includes an important bug fix).
